When the heat is on, sweat happens. Temperature, humidity, stress or activity can trigger perspiration, it’s natural. But sweat stains aren’t. When moisture combines with deodorant, hard-to-remove yellowing or white residue can occur. Too much product is often the culprit – apply one thin layer and allow it to completely dry. There’s no evidence that more is better at protecting against moisture or odor. A little is enough. Good old-fashioned dress shields do a good job of containing perspiration and protecting your garment. Men should wear cotton undershirts to absorb dampness. When a stain does happen, bring the garment to us. We use professional stain removal products and techniques, specific for fabric type and finish.
